Detailed implementation manners

[0017] The principles and features of the present invention will be described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of the present invention.

[0018] Please refer to Figures 1-9 , as shown in the figure, a dust removal device for building construction provided in this embodiment, please refer to Figures 1-4 , including a flow-limiting pipe 1. Both ends of the flow-limiting pipe 1 are fixedly installed with a diversion pipe 2 by welding. One end of the diversion pipe 2 is fixedly installed with a connecting pipe 3 by bolt connection. A bypass pipe 4 is fixedly installed on the outer surface of the diversion pipe 2 by welding. One end of the bypass pipe 4 is fixedly installed with a side pipe 5 by clamping. A nozzle 6 is fixedly installed at a position near the middle on the top of the outer surface of the side pipe 5 by welding. By fixedly installing a bypass pipe 4 on the outer surface of the diversion pipe 2 by welding and fixedly installing a side pipe 5 at one end of the bypass pipe 4 by clamping, the nozzle 6 is connected to the flow-limiting pipe 1 in parallel. When the nozzle 6 is blocked after long-term operation, it does not affect the normal flow of water inside the flow-limiting pipe 1, avoiding the problem that the inside of the nozzle 6 is blocked by scale accumulation and extends to the inside of the flow-limiting pipe 1, resulting in blockage of the fluid flow and reduction of the subsequent water supply efficiency of the nozzle 6, and improving the stability of the operation of the device.

[0019] At the positions near both ends of the top and bottom of the flow-limiting pipe 1, extension plates 7 are fixedly installed by welding. One end of the extension plate 7 is fixedly installed with a control device 8 by bolt connection. On the top and bottom of the inner cavity of the flow-limiting pipe 1, slide rails 12 are fixedly installed by bolt connection.

[0020] Further, please refer to Figures 4-6 , the control device 8 includes a control board 81. Both ends of the control board 81 are movably sleeved with connecting plates 82 through shaft-hole cooperation. One end of the connecting plate 82 is movably sleeved with a travel plate 83 through shaft-hole cooperation. A chute 84 is arranged on the top of the travel plate 83 by casting. One side of the travel plate 83 is fixedly installed with a telescopic machine 85 by bolt connection. One end of the telescopic machine 85 is fixedly installed at one end of the extension plate 7 by bolt connection. One end of the output shaft of the telescopic machine 85 penetrates through the flow-limiting pipe 1 and extends into the interior of the flow-limiting pipe 1.

[0021] Further, please refer to Figure 4 , a laser emitter 10 is fixedly installed by welding at a position near one end of the bottom of the flow-limiting pipe 1, and a photosensitive plate 11 is fixedly installed by welding at a position near the other end of the bottom of the flow-limiting pipe 1. The axis of the laser emitter 10 and the axis of the photosensitive plate 11 are on the same center line.

[0022] Further, please refer to Figures 4-5 , the signal output end of the photosensitive plate 11 is connected to the input end of the telescopic machine 85 by wireless signal connection.

[0023] It can be understood that since the nozzle 6 and the flow-limiting pipe 1 are in a parallel state, when the output end of the telescopic machine 85 extends into the interior of the flow-limiting pipe 1, the control boards 81 at the top and bottom of the inner cavity of the flow-limiting pipe 1 are pushed closer to each other. At this time, the flow resistance of the water inside the flow-limiting pipe 1 increases, causing the liquid pressure inside the pipe of the side pipe 5 to increase, thereby controlling the nozzle 6 to spray more water mist per unit time, thus improving its dust removal effect. When the output shaft of the telescopic machine 85 retracts, based on the same principle, the control boards 81 at the top and bottom of the inner cavity of the flow-limiting pipe 1 move away from each other, controlling the nozzle 6 to reduce the water mist touched per unit time, thereby realizing the control of the spraying efficiency of the nozzle 6.

[0024] In addition, the axis of the laser emitter 10 and the axis of the photosensitive plate 11 are on the same center line, so that the light emitted by the laser emitter 10 can be projected onto the surface of the photosensitive plate 11. When there is less dust, the light intensity received by the photosensitive plate 11 is higher; when there is more dust, the light intensity received by the photosensitive plate 11 is lower. And the signal output end of the photosensitive plate 11 is connected to the input end of the telescopic machine 85 by means of a wireless signal connection, so as to control the telescopic movement of the telescopic machine 85. When the telescopic machine 85 extends and makes the control plates 81 approach each other, the spraying efficiency of the nozzle 6 is improved and its dust removal effect is enhanced. When there is less dust, the telescopic machine 85 retracts and makes the control plates 81 move away from each other, the spraying effect of the nozzle 6 is reduced and the water resource is saved. Thus, it is ensured that the amount of water mist sprayed by each nozzle 6 can be automatically adjusted according to the dust amount in the surrounding environment, greatly improving the automation of the device, and the water consumption of the device is at the optimal level.

[0025] Further, an air flow device 9 is fixedly installed on the back of the flow limiting pipe 1. The air flow device 9 includes a rotating chamber 91. A main shaft 92 is sleeved in the rotating chamber 91. Impact vanes 93 are provided on the main shaft 92. A rotating shaft 94 is fixedly installed at the top of the main shaft 92. A fan blade 95 is arranged on the rotating shaft 94. The impact vanes 93 extend into the flow limiting pipe 1, and the impact vanes 93 are located between the control devices 8.

[0026] Specifically, please refer to Figures 7-9 , the air flow device 9 is fixedly installed on the back of the flow limiting pipe 1 by welding. The air flow device 9 includes a rotating chamber 91. The inner cavity of the rotating chamber 91 is communicated with the inner cavity of the flow limiting pipe 1. The main shaft 92 is movably sleeved in the rotating chamber 91 through a shaft hole fit. Impact vanes 93 are arranged on the outer surface of the main shaft 92. The rotating shaft 94 is fixedly installed at the top of the main shaft 92 by bolt connection. A fan blade 95 is arranged on the outer surface of the rotating shaft 94.

[0027] More specifically, please refer to Figures 4-5 and Figure 9 , the impact vanes 93 extend into the interior of the flow limiting pipe 1, and the impact vanes 93 inside the flow limiting pipe 1 are located between the control devices 8.

[0028] It can be understood that during use, the nozzle 6 and the flow limiting pipe 1 are in a parallel state. When the output end of the telescopic machine 85 extends into the interior of the flow limiting pipe 1, it pushes the control plates 81 at the top and bottom of the inner cavity of the flow limiting pipe 1 to approach each other. At this time, the flow resistance of the water inside the flow limiting pipe 1 increases, so that the liquid pressure inside the side pipe 5 pipeline increases, thereby controlling the nozzle 6 to spray more water mist per unit time. When the output shaft of the telescopic machine 85 retracts, by the same principle, the control plates 81 at the top and bottom of the inner cavity of the flow limiting pipe 1 move away from each other, controlling the nozzle 6 to reduce the water mist sprayed per unit time, so as to realize the control of the spraying efficiency of the nozzle 6;

[0029] The light emitted by the laser transmitter 10 can be projected onto the surface of the photosensitive plate 11. When there is less dust, the light intensity received by the photosensitive plate 11 is higher. When there is more dust, the light intensity received by the photosensitive plate 11 is weaker. The signal output end of the photosensitive plate 11 is connected to the input end of the telescopic machine 85 by wireless signal connection, thereby controlling the telescopic machine 85 to extend and bring the control panels 81 closer to each other, thereby improving the spray efficiency of the nozzle 6 and enhancing its dust removal effect. When there is less dust, the telescopic machine 85 retracts and moves the control panels 81 away from each other, thereby reducing the spray effect of the nozzle 6 and achieving the effect of saving water resources, thereby ensuring that the amount of water mist sprayed by each nozzle 6 can be automatically regulated according to the amount of dust in the surrounding environment.

[0030] The water flow inside the flow-limiting tube 1 will impact the impact blade 93 during the flow process, thereby driving the fan blade 95 to rotate through the main shaft 92 and the rotating shaft 94, thereby generating a vertical upward airflow on one side of the nozzle 6. At this time, the water mist and dust sprayed by the nozzle 6 will move upward under the action of the airflow, thereby increasing the height between the water mist and the ground, so that it can have more time to be fully mixed before landing, and the maximum height that the water mist can reach is increased, and there is sufficient time to disperse during the falling process; when the control plates 81 are close to each other, due to the reduction of the channel cross-sectional area, the flow rate of the water flow is accelerated when passing through the gap between the control plates 81, thereby increasing the impact force on the impact blade 93, so that the rotation speed of the fan blade 95 is increased, thereby generating a stronger airflow, so that the airflow intensity generated by the rotation of the fan blade 95 is proportional to the amount of water mist sprayed by the nozzle 6, so that the larger the amount of water mist sprayed, the higher the maximum height that the water mist can reach, so that it has sufficient time to fall and disperse, and the coverage range is also larger, further improving the dust removal effect.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
